At the time, he was more interested in finding a good, affordable meal than contemplating the sheer awesomeness of the organ he was eating. Years later, Jasanoff began studying the brain as part of his...

I know a lot of adults who don’t like to cook, but I’ve never met a child who doesn’t enjoy playing with a toy kitchen — or one who doesn’t want to help chop vegetables for dinner.
